Climate change and associated environmental alterations affect plant communities, potentially decoupling links between plants their soil microbial communities. This may in turn processes like litter decomposition, an important function that controls nutrient carbon cycling as well many other ecosystem processes. Microbial decomposers have been proposed to specialize, being able easier decompose from its ‘home’ community than what is termed the home field advantage (HFA) hypothesis. We report a decomposition experiment including four alpine meadow communities spread along geographical gradient ranged Atlas Morocco Iberian Peninsula Swiss Alps. tested whether rate would differ depending on origin, expecting interactions be at core of responses. expected find HFA all very negative neutral positive our gradient, variation could attributed interaction with traits, linked relative abundance groups performing specific functions. Litter depended quality fungal community, which seemed adapted deal poor-quality, recalcitrant litter, leading HFA. plays role well, indirectly through composition. Phyllosphere competed when interaction, fact blurred results some previous experiments. In summary, there clear systems low-quality requires specialised maximize decomposition. By contrast, high-quality, easy dealt by any decomposer not showing evidence

Nitrogen addition alters soil organic carbon (SOC) and total nitrogen (TN) accumulation in forest ecosystems, but the responses of SOC TN sequestration rates dynamics to ecosystems worldwide remain unclear. This study conducted a global analysis evaluate effects application rate, duration (time), humidity on from 257 data points (63 articles). increased by 4.48% 10.18%, respectively.

These results enhance our understanding cycling soils context deposition.

ABSTRACT Investigating the differences among plant functional types (PFTs) and their responses to N deposition is crucial for predicting carbon nutrient cycles improving forest management strategies. Our research aimed examine decomposition rates loss of leaf litter fine roots from ancient recently evolved species response deposition. We hypothesized that (1) leaves tree decomposes slower than those due higher C:N ratios structural compound content; (2) effect addition on differs across different stages influenced by associated PFT; (3) morphology substrate quality are key predictors both species. Field experiments were conducted with under control N‐addition treatment (10 g·m −2 ·a −1 ), focusing three The rate constants ( k values) lower species, values 1.01 1.68 conditions, 1.07 1.08 addition. For roots, had only (1.05 1.40), whereas no significant observed between conditions. Furthermore, residual in was compared controls, while such distinct patterns this study provide valuable insights into complexity deposition, highlighting importance considering PFTs organ ecosystem responses.

Global hydrological cycles are shifting due to climate change, and projected increases in the frequency intensity of extreme precipitation events will likely affect essential ecosystem processes driven by climate, such as forest decomposition. Our objective was determine effects drought intense rainfall on leaf litter wood decomposition rates. We used a manipulation experiment demonstrate that projections for Northeastern United States significantly impact but not variations substrate quality continue drive differences found high reduced compared historic patterns. The median mass remaining stakes after three years within drought, control, inundation treatments 84.2%, 57.0%, 67.5%, respectively. Furthermore, labile substrates decomposed more rapidly than recalcitrant types. Thus, our findings suggest greater sensitivity changing regimes litter. Since represents substantial carbon pool, results underscore possible significant impacts scenarios functions, including cycling sequestration.
